Effect of Supplementation Selenium and Vitamin E on Blood and Stress Parameters of Awassi Lamb

Abstract

The study was established in local farm sheep in Muwafaqia / Wasit - Iraq, from 1/10/2018 until 15/1/2019, to evaluate the effect of adding selenium with or without Vitamin E on some of the physiological characteristics of Awassi male lambs. Sixteen lambs were selected after weaning with an average weight of (24.30) kg and aged (3-4) months. All lambs fed 2% of body weight with a concentrated diet and randomly divided into (4) groups. Control group (no additives), Selenium group (0.4 mg selenium), Vitamin group (100 mg vitamin E) and combination of selenium + vitamin E group (0.4 mg selenium + 100 mg vitamin E) per kg dietary dry matter for 90 days. At the end of the experiment, blood parameters (white blood cell (WBC), red blood cell (RBC), packed cell volume (PCV), hemoglobin (HB), mean concentration hemoglobin (MCH), and mean concentration hemoglobin count (MCHC) and stress parameters were measured. The result showed selenium + vitamin E and selenium treatments significantly increased (p <0.05) in PCV as compared with vitamin treatment and the control group. While treatment of vitamin significantly increased (p <0.05) in hemoglobin concentration compared to treatment of combination selenium + vitamin E. Stress parameters such as respiratory rate and heartbeat decreased significantly (p <0.05) in treatment of combination selenium + vitamin E compared to other treatments. There were no significant differences between the study treatments in the WBC count.
